What is a molded material that can retain its shape?
A common example of a molded material that can retain its shape is plastic. When heated and molded into a specific form, plastic cools and solidifies to maintain that shape. This property makes plastic widely used in manufacturing for various products due to its durability and versatility.
Easily taking shape or easily molded contains the letters duct?
The word that fits the description is "ductile." Ductile refers to a material's ability to be easily shaped or molded without breaking.
Does wood have a definite shape?
No, wood does not have a definite shape. It can be cut, carved, or molded into various forms based on the desired outcome. Wood is a versatile material that can be shaped and customized for different uses.
What metal returns into its original shape when it is heated after it was bent?
The metal that returns to its original shape when heated after being bent is called memory metal or shape memory alloy, such as nitinol. This material has the ability to "remember" its original shape and can revert to it when heated above a certain temperature. It is used in various applications, including in medical devices and robotics.
Why does zinc bend when it is heated?
When zinc is heated, it expands due to increased kinetic energy of its atoms. This expansion causes the zinc to bend, as its shape is altered by the unequal expansion of different parts of the material.
What is a molded material that can retain its shape?
A common example of a molded material that can retain its shape is plastic. When heated and molded into a specific form, plastic cools and solidifies to maintain that shape. This property makes plastic widely used in manufacturing for various products due to its durability and versatility.
Describe how glass is prepared?
Glass is heated in a furnace until it begins to flow. It can then be blown or molded into shape.
Who made plastic bags?
The first man-made plastic was created by Alexander Parkes who publicly demonstrated it at the 1862 Great International Exhibition in London. The material called Parkesine was an organic material derived from cellulose that once heated could be molded, and retained its shape when cooled

Easily taking shape or easily molded contains the letters duct?
The word that fits the description is "ductile." Ductile refers to a material's ability to be easily shaped or molded without breaking.
Why sand is used as a molding material?
Sand is used as a molding material in casting processes because of its ability to hold its shape well, withstand high temperatures without melting, and allow for easy removal of the molded object. Additionally, sand is readily available, inexpensive, and easy to work with, making it a common choice for casting applications.
What are malleable wax unbaked clay baked clay or metal?
Malleable wax is a pliable material that can be shaped and molded before hardening. Unbaked clay is clay that has not been fired in a kiln, so it remains soft and can be reworked. Baked clay has been fired in a kiln, making it hard and durable. Metal can be shaped and molded when heated, but once cooled and hardened, it retains its shape.
How do factories make bouncy balls?
Bouncy balls are typically made by mixing rubber or polymer material with various chemicals and colorants. This mixture is then heated and molded into shape, before being cooled and packaged for sale. The specific manufacturing process can vary depending on the manufacturer and the desired characteristics of the ball.
Does wood have a definite shape?
No, wood does not have a definite shape. It can be cut, carved, or molded into various forms based on the desired outcome. Wood is a versatile material that can be shaped and customized for different uses.

This material has the ability to "remember" its original shape and can revert to it when heated above a certain temperature. It is used in various applications, including in medical devices and robotics.
What is the term plastic memory?
"Plastic memory" refers to a phenomenon in which a material temporarily retains a deformation or shape after being subjected to stress, but eventually returns to its original shape once the stress is removed. This is often seen in certain types of plastics or materials that exhibit viscoelastic behavior.
Why does zinc bend when it is heated?
When zinc is heated, it expands due to increased kinetic energy of its atoms. This expansion causes the zinc to bend, as its shape is altered by the unequal expansion of different parts of the material.
